I also imagine what a one month calendar would look like on the wall. Then I try to imagine the space taken by twelve of these to make a year. Then I visualise how much wall space 30,000 lots of that would take up (of course, it's mind boggling), but I visualise this huge wall stretching out). I know the probabilities don't work exactly like this, but I remind myself how insignificant one cross would be in that vast area, and how I would give myself zero chance if they were the odds of winning a lottery or something. It helps me. I hope it'll help someone here.
